Title: Piston for internal combustion engine
Inventor: IRIE YASUTAKA
IPC: F16J1/09
Filed: 1989-09-29
Abstract: PURPOSE:To improve reliability of a high output internal combustion engine simultaneously with reduction of the manufacturing cost by providing an annular rib, an outer peripheral fluid chamber, an outer peripheral cooling hole, an outer peripheral nozzle, an inner peripheral fluid chamber, and an inner peripheral nozzle. CONSTITUTION:Cooling fluid flows in a piston through a piston rod. After it flows as shown by an arrow mark to cool the outside, it is discharged to the outside. Feed fluid first flows in a feed fluid chamber 11 and injected through a plurality of outer peripheral nozzles 12 to effectively cool a piston crown shoulder part 1a, having a high heat load, and a flame contact surface 1c, having a high heat load, through the inner surface of an outer peripheral cooling hole 7, and is guided to an inner fluid chamber 13 through an outer peripheral fluid chamber 8 and a communicating passage 15. Fluid injected through an inner peripheral nozzle 14 cools the flame contact surface 1c, having a high heat load, through the inner surface of an annular inner peripheral fluid chamber 9. The fluid flows through a cooling chamber 16 as it cools the cooling chamber and flows in a central fluid chamber 10 and is discharged to the outside. This constitution suppresses the generation of a thermal stress by means of a jet through two nozzles 12 and 14, and reduces a stress generated due to a gas pressure.

Title: Gate pulse generating circuit for ultrasonic measuring device
Inventor: NISHIZUKA KEN
IPC: G01N29/38
Filed: 1992-08-28
Abstract: PURPOSE:To reduce delay time from reception of the surface echo o generation of a gate pulse. CONSTITUTION:Passed time on and after a synchronous signal 33 is counted by a counter circuit 2, and count values until reception of the surface echo are held until the next measuring cycle by a latch circuit 3.
